Title: Improvements in internal combustion engines
IPC: F02D17/00
Filed: 1919-09-11
Abstract: 154,727. Dougall, P. Sept. 11, 1919. Regulating.-Relates to valve-gear for gasengines in which governing is effected by allowing the gas-valve 4 to remain closed when the speed is excessive, the exhaust valve, or an independent valve 9 being opened on the stroke following the idle suction stroke, so that the air that has been drawn in is discharged and no power is lost by air compression. According to the invention, when the governor lever 6 raises the die 3 to cut out the gas-valve, it also interposes a die 18 between a cam-actuated tappet rod 14 and a valve-actuating rod 12, so that the cam 1 actuates the air-releasevalve 9. The die 18 is slotted so as to slide on. the squared end of a rod 20 connected to thegovernor lever.

Abstract: 265,644. Ryves, R. A., Williams, M. E., and Hall, L. Sept. 7, 1925. Stream-cutting machines. - A continuouslymoving stream of concrete or like plastic material in a tile or slab-making machine is adapted to be cut lengthwise into strips by means which are so arranged or shaped that the period of a cutting operation is more prolonged than usual, the cutting consisting either of a set of rotatablymounted disc knives c<1>, c<2>, c<3> arranged end to end and so that each successive disc cuts the material a little deeper than the preceding disc, as shown in Fig. 1, or of a fixed blade l having its cutting edge set at an upward and backward inclination to the stream, as shown in Fig. 3. The discs c<1>, c<2> are rotatably mounted in yoke-pieces d bolted to a bridge plate e, and the disc c<3> is carried from the plate e by a yoke d', a spring h being disposed between the yoke d<1> and bridge. To ensure that the disc c<3> shall cut very nearly to the bottom of the stream, the yoke d<1> may have lugs adapted to engage stops k. The edges of the discs may have annular projections c<4>, c<5>, c<6> in order to round the edges of the tiles. Where two or more side-by-side sets of discs are employed, the axles i may carry two or more discs. The cutter l, Fig. 3, is mounted from a bridge by means of axles m, m<1> in yoke-pieces n, n<1> which are suspended by bolts o, o<1>. The yoke n<1> is sustained by a spring q, which is attached to the bolt o<1>. Lugs r on the yoke n<1> and stops s on the plate e ensure that the blade shall cut nearly to the bottom of the stream. The edge of the knife may be progressively developed so as to give any desired shape to the upper and lower edges of the tiles. A separate former u may be provided to round the edges of the tiles. The pallets may be grooved to receive the cutting blade or discs. The discs or blade may be supported from a bridge below the stream or from bridges above and below the, stream.

Title: Improvements in and relating to machines for washing bottles
IPC: B08B9/42
Filed: 1920-07-28
Abstract: 168,755. Schmidt, E. A. July 28, 1920. Bottles, washing.-The bottles are carried by a conveyer chain through a hot-water tank so as to be filled with water and then subjected to a blast of compressed air by inserted nozzles, whereby the impurities are blown out, the endless conveyer carrying the bottles one-and-a-half times round the conveyer circuit so that the bottles are first exposed to the action of the steam above the hot water, then filled with water and subjected to the air blast, after which the bottles are re-filled with water, carried round in an inverted position and removed from the tank to a rinsing-machine. In the arrangement shown, the bottles are fed from a tray 23 into the alternate links 5 of a conveyer band 4 which is operated intermittently so as to convey the bottles in the direction of the arrow. During this movement, they are heated by the steam at the top of the tank before immersion under the water. When positioned under the funnels 51, nozzles 42 communicating through a flexible pipe 43 with an air tank 40 supplied by a compressor 39 are inserted into the bottles by the operation of a lever 46 actuated by a cam on the shaft 20. A valve is then opened, and a jet of compressed air supplied through the nozzles blows the impurities out of each bottle. After this cleaning operation, the conveyer carries the bottles round the wheels 6, 7 and opposite a discharging device 33, which is operated from the shaft 20, to eject them on to a tray 35. This tray is then tilted, and the bottles pass down an inclined guide 50 to a rinsing-wheel 57. The trays 23, 35 are operated by links and levers 25 - - 28 and 36, 37 from the shafts 20, 17 respectively.
